How Apigenin Promotes Relaxation
Apigenin helps your brain embrace its natural calming signals. Unlike stimulants that ramp up your nervous system, this flavonoid works by amplifying the messages that tell your brain to relax and take it easy.
How Apigenin Works with GABA Receptors
Apigenin interacts with benzodiazepine receptors on the GABA_A sub-type in your brain. By binding to these receptors, it boosts GABA signaling, which encourages a sense of calm. This effect reduces anxiety and promotes relaxation without causing the muscle relaxation side effects often linked to pharmaceutical benzodiazepines when taken at standard doses.
It doesn’t stop there - apigenin also slows down the release of glutamate, the brain's primary excitatory neurotransmitter, particularly in the hippocampus. This dual action reduces stimulating signals while encouraging relaxation. Studies on rats suggest that apigenin may influence GABAergic pathways in ways that don’t rely solely on the traditional GABA-benzodiazepine binding site, hinting at a more complex interaction with the GABA_A receptor.
This fine-tuned modulation of neurotransmitters lays the groundwork for apigenin's role in managing stress hormones effectively.
Lowering Cortisol and Managing Stress
Apigenin doesn’t just calm your brain - it also targets stress hormones directly. In human adrenal cells, a 12.5μM concentration of apigenin reduced cortisol levels to 47.5% of the control value, cutting cortisol production by more than half at its source.
In a clinical study with 26 participants, consuming 500 mg of flavonoids (including apigenin) daily for four weeks significantly reduced salivary cortisol levels. Beyond cortisol, apigenin also lowers corticosterone (the rodent equivalent of cortisol) and boosts levels of sleep-promoting biomarkers like serotonin and BDNF. Lower cortisol not only eases stress but also helps your body shift from a "fight or flight" state to a "rest and digest" mode, paving the way for restorative deep sleep.
How Apigenin Improves Deep Sleep Quality
Once apigenin calms your nervous system and reduces stress hormones, it plays a key role in enhancing the quality of your sleep. This isn't just about drifting off faster - it’s about staying in those restorative sleep stages that leave you feeling refreshed when you wake up.
Effects on Sleep Stages
Apigenin works by interacting with chloride ion channels in the forebrain, which reduces overall neuronal activity. This helps smooth the transition into deeper sleep phases. Studies indicate that apigenin not only extends the duration of sleep but also shortens the time it takes to fall asleep.
It doesn’t stop there. Apigenin also helps regulate your sleep-wake cycle. By inhibiting CD38, it preserves NAD+ levels, which are crucial for cellular energy and maintaining your circadian rhythm. On top of that, apigenin boosts Brain-Derived Neurotrophic Factor (BDNF) and phosphorylated CREB in the hippocampus - both of which are linked to high-quality, restorative sleep. Additionally, it reduces neuroinflammation by lowering pro-inflammatory markers like TNF-α and IL-6, which is especially important since chronic sleep deprivation can lead to significant brain inflammation.
Combined Effects with Other Sleep Ingredients
Apigenin doesn’t just work well on its own - it becomes even more effective when paired with other sleep-supporting ingredients. For instance, combining apigenin with melatonin can amplify its benefits. While apigenin promotes relaxation by activating GABAergic pathways and lowering cortisol, melatonin focuses on regulating your circadian rhythm. Studies have shown that melatonin is particularly effective at reducing the time it takes to fall asleep when your natural levels are low:
"Melatonin can reduce sleep onset latency by 5–22 minutes... The sleep-inducing capabilities of melatonin seem even more pronounced when melatonin is administered when endogenous secretion is minimal." - Cathy A. Goldstein and Helen J. Burgess, Journal of Clinical Sleep Medicine
When used together, apigenin and melatonin tackle different aspects of sleep. Apigenin extends deep sleep phases, while melatonin improves sleep onset. Multi-ingredient formulations like RST Sleep take this synergy further by combining apigenin with extended-release melatonin, glycine, phosphatidylserine, and magnolia bark. This blend addresses both falling asleep (via GABA activation and circadian signaling) and staying asleep (through sustained melatonin release and stress hormone regulation). Together, these ingredients provide comprehensive support for a night of deep, restorative sleep.
How to Use Apigenin for Better Sleep
Incorporating apigenin into your routine can help promote better sleep. Whether you choose to get it from food or supplements, the right dosage and timing are key to maximizing its calming effects. Here’s how to make the most of apigenin’s benefits for relaxation and deeper sleep.
Recommended Dosage
For best results, take 50 mg of apigenin about 30–60 minutes before bedtime. This helps activate GABA receptors, which play a role in calming the mind. While you might notice some effects within 2–4 days, the full benefits often become apparent after several weeks of consistent use.
Clinical studies often use chamomile extract as a source of apigenin. These extracts, which typically contain 0.8% to 1.2% apigenin by weight, are administered in doses ranging from 540 mg to 1,500 mg per day. Since chamomile extract contains only a small percentage of apigenin, these higher doses provide an amount comparable to the 50 mg found in most apigenin supplements. If supplements aren’t your preference, you can also turn to certain foods to naturally increase your intake.
Natural Food Sources of Apigenin
Although food sources of apigenin provide smaller amounts, they can still contribute to your daily intake. Most adults get less than 5 mg of apigenin per day from their diets. Chamomile tea is one of the easiest and most relaxing ways to add apigenin to your evening routine.
Other natural sources include dried herbs like parsley, thyme, basil, oregano, and tarragon. Vegetables such as celery and onions, along with fruits like oranges and grapefruit, also contain small amounts of apigenin. While these foods won’t match the potency of supplements, they can complement your intake.
Supplement Tips for Night Shift Workers
If you work night shifts or have an irregular schedule, apigenin can be a practical option to support restful sleep. Unlike many traditional sleep aids, it’s non-habit forming and doesn’t leave you feeling groggy the next day. For consistent results, take 50 mg of apigenin 30–60 minutes before your designated sleep period, no matter the time of day. Its ability to reduce cortisol levels can also help manage stress, which is often heightened by irregular work hours.
To enhance its effects, you might pair apigenin with other non-sedating ingredients like magnesium L-threonate or L-theanine. Products like RST Sleep combine apigenin with extended-release melatonin, glycine, phosphatidylserine, and magnolia bark to help reset your sleep cycle. This approach promotes restorative sleep without the grogginess, ensuring you wake up ready to tackle your day - or night.
